Wire is located in Switzerland. Outside the EU.
I do use Switzerland as an exit for my vpn though yes.
Truth is, Euros don't care about privacy. The endgame will probably be to host this stuff in the third world or something, like pirates do
Switzerland created a new set of surveillance laws in January, that far exceed anything inside the EU. Which means that EU laws are irrelevant, when talking about a company inside Switzerland - you should be talking about what they actually use!
